Bls Spiral AGM Battery Red Top 12V45ah Starting L2-400 CCA 750A Low Temperature

BLS Spiral AGM battery yello top 12V45AH Modified vehicle car Low temperature - racing starting battery CCAB750A Spare RV

The spiral wound technique was originally derived from the U.S. military, for application of armored vehicles, tanks and other military vehicles.In 2004, BLS firstly introduced this new technique ,which breaked the monopoly of other brand battery and can be replaced completely. Meanwhile ,we have gained several patent certificates for this battery technique.By using the alloy with very high hydrogen to form the pallet with a special processing manufacturing grid, stepped by suitable matching process of the positive and negative active material quality, making the negative hydrogen evolution process to be maximumly inhibited. Meanwhile, the excessive oxygen generated by positive over-charge reaches the cathode, make reaction with the lead there ,and result in water. The water is protected from loss and achieves maintenance free of battery.



The battery can be normally used at -50ºC, and it won't swell or distort at the high temperature of 80 degree. 
Its largest starting current is as large as 30 times, which is three times as common batteries.
It can be started as much as 15000 times, which is 3 times as common storage batteries.  
It can charge more than 95% within 40 minutes. 
There is no flowing liquid inside, so it can be placed at any direction. 
It can bear the vibration of 4G (33HZ) for at least 12 hours.
100% deep cycling discharge can reach 300 times, and its life can be as long as 10 years. 
Its self-discharge rate is only 3% every month, and it can start vehicles when it is placed one year later. 

BLS serial battery is fabricated with high pure lead, it has much less side reaction than the normal battery. Current is well Distributed and active material is bigger than surface area with thin plate and special structure. Therefore, BLS can be charged With trickle current, and reach 90% charge efficiency even at cloudy or rainy days.


BLS introduced special low temperature active material formula, and achieves 3 folds of electrode surface area than normal Battery, which reduces the internal resistance to a great extent, and then makes itself to be chargeable under low temperature.In case of high temperature, the grid corrosion rate is usually very high, this time BLS' S cold-rolling pure lead grid has much Higher corrosion resistance capability than normal lead alloy grid, so BLS has much longer working life. At the same time, BLS Can avoid severe water loss, swelling or transformation by cylindrical structure and 50kap open valve pressure under high Temperature, which can ensure its long working life.


BLS serial battery adopted much less electrolyte by 30% than normal battery, at the same time, its electrolyte is completely.Absorbed in the plate and AGM separator, which results in that there is no free electrolyte in the battery. So, BLS can be placed t random position without leakage.

Because BLS has extremely low internal resistance, so it can output high stable voltage under middle and high rate Discharge. In addition, fast charge is possible, 95% plus capability may be charged in 40mins.

When a battery is applied in cell system, it can't be charged 100% after being discharged each time, then the battery begins to work under partial state or charge(PSOC),after a long period, part of active materials will not be utilized, and lose their active capability ,then leads to the failure of the batteries immediately. But BLS's grid is only 0.6mm~0.9mm in thickness, and with its special separator, its internal resistance is only one third of the normal battery's, and its capacity can be recovered to the common level after long period shelf without particular charge method.Moreover, it can stand 4G(33HZ) vibration for 12 hours and 6G vibration for 4 hours. 




 

One-stop solution

Lithium / LiFePo4 battery packs, accept customized, OEM sevices,
We will respond within 1 business day or less.
Anyone who is open dispute without contact us , no warranty! add blacklist .
No matter what problems is , we can slove them,  Any questions please contact us first !

No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped. Customers should configure a BMS which is used for strictly monitoring, management and protection. Properly connect the terminals of positive and negative of the batteries. The reversal charging is forbidden. If the polarity is reversed, the battery will be damaged and safety problem may occur. If the batteries kept unused for a long time, it should be charged and discharged at the standard model every six months. Store the battery in the state of 30% SOC (voltage scope: 3.275V~3.305V).

 Appearance Without break, distortion, contamination, leakage.

About Shipping:

1. we usually send out battery by international commercial express, UPS ,FedEx ;but now battery belong to some dangerous goods in some countries , so we send them by special line.

2. It takes 8-15 days by express send to destination ( not including the Lead Time ) ,if send by special line may takes more than 25 days. 

3. Battery goods belong to sensitive items , we produce the best battery , so welcome customer come to our warehouse.

About  Samples Customs duties & taxes:

EU Member Countries,Custom duties and custom clearance expenses are included. Canada,United States,Russian Federation,UK,Japan Thailand,Singapore,Vietnam,Taiwan,Malaysia, Philippines.Custom duties and custom clearance expenses are included.Other countries dos not include Customs duties & taxes. If you have any questions, please contact us online.

These situations not provide return nor refund:

1: after the assembly or assembly process happen any problem, such as the protection board connected to the wrong wire burned lead to battery damage, charger failure, the assembly error or unbalanced assembly, etc.  

2: For damage caused , such as battery bulge/ welded, battery pack without protection BMS caused by charging.  Tip: These products are batteries only, without protection board, you need to purchase a match one! You can check our shop and search BMS. 

3: Courier and logistics In addition, because the battery is prohibited product, many courier and logistics are unable to send, the arrival will indeed be slower, so please wait patiently after place an order. Can Not give us bad feedback due to the courier company or because of the courier service slow or other factors.  open dispute will be unacceptable. Sorry for any inconvenience.
